What are the differences between net, network, mesh and grid? If I have a look at the OED entries, I have a feeling of rather a circular definition: mesh Material made of a network of wire or thread... net A piece of open-meshed material... grid A network of lines that cross each other... Could you list some most commo...

Astroturfing is a word used to describe a fake or counterfeit grassroots campaign. The clever term is derived from the notion that one kind of fake grass is astroturf. Another more niche example is from mathematics. We call the "germ" of a function the part at the bottom of a stalk in some sheaf. We call this a germ be...

There is always a debate around Earth Hour every year, and the opposite side of Earth Hour usually claims that The (sudden) decrease and increase of the power usage in the start and end of Earth Hour will cause much more power loss (than the save of power), and even do damage to the power supply system. Is this stateme...

I'm currently working on some graph theory, and I'm checking the robustness of graphs, by removing random vertices from a graph and then check how many vertices are outside the giant component. Then I'll do that for a lot of vertices, and plot them using ListPlot. This takes along time to calculate, is there a way I ca...

If two stick two magnets the mass will be less than sum of the individual magnets. They lose certain mass while they stick together. Probably, they release some energy. My question is: when the magnets are separated, whether their original mass is restored to its original level? If that is right then after performing s...

Possibly two questions in here: Are these sentence constructions logical, and if they are, why are they different? I swam across the Ocmulgee River. I swam across the Pacific Ocean. I swam across the Red Sea. I swam across Lake Winnipeg. I can't think of a way of phrasing the lake example while using an article with a ...

There is a similar question that gives a bit of an explanation, but little mathematical proof here: force applied not on the center of mass I would like mathematical proof that shows that the velocity of a rigid body when a force is applied to the center of mass is equal to the velocity of the same rigid body when the ...

Via Cantor's back-and-forth method we know that the linearly ordered set of all rational numbers and the linearly ordered set of all real algebraic numbers are isomorphic. But from the point of view of what people usually do with rational numbers or with algebraic numbers, the order isomorphisms yielded by Cantor's pro...

Okay, so recently I ended up saying this: Well, that is unfortunate... sometimes it happens, sometimes it doesn't. Okay. You know, just saying "Sometimes it happens" already tells you that something happens sometimes and other times it doesn't. But, sometimes, I need to make very clear that this "something" doesn't hap...

I am working on displaying source code for which I pass a path to a macro.

I am aware that the universally accepted style is to put an apostrophe-s at the end of the second possessor's name.

Initialisms are pronounced as words and acronyms are spelt letters. However, some words sound the same, said and spelt. e.g. Input Output can be abbreviated as IO.

The plural of 'passerby' is 'passersby' with an 's' acting like an infix (W-B says that this is the only plural form of the word). This seems like a very interesting exception, so I thought I would ask a question. Are there any other English words that are made plural by an 's' put inside the noun? One criterion has to...

I am confused about some definitions in logic/ axiomatic set theory: We stated in our logic lecture the ZFC axioms and called the members of a ZFC-model "sets".

I have observed while driving at night the yellow marks on road seem white. What I understand is the color of an object is the visible light wavelengths it does not absorb.

What is wind? I think it is kind of a vibration of air particles. If so, is it a longitudinal or a transverse wave? Or is it just a bunch of air particles being pushed? Smells disperse in wind so the latter explanation might be a better. And breath also consists of movement of air particles. But how can wind travel so ...

Lately, I have been watching sparks while connecting my electronic devices and I can notice that electricity is kind of blue, and theoretically it's blue because it reflects blue wavelengths??
